Answer:
The blue area is the difference between the area of the 8 ft diameter rug and the area of the 6 ft diameter rug.
Step-by-step explanation:
From each diameter, you can figure out the appropriate radius. Then find the area of the larger circle & subtract from that the area of the smaller circle, using the formula Area = pi•radius2 for each circle.

Answer:
Step-by-step explanation:
Given:
The radius of the circle is 6 inches.
And the central angle is 110 degree.
The area of the sector = -------(1)
Where
Put radius and central angle value in equation 1.
area of the sector =
area of the sector =
Therefore, the area of the sector is
Answer:
4 miles per hour.
Step-by-step explanation:
2 hours = 28 miles downstream; 14 miles per hour
3 hours = 18 miles upstream; 6 miles per hour
The boat went faster when going downstream meaning the current is going towards up stream. I would find the average speed, (14+6=20/2=10 m/h average) and determine subtract the average from the speed from wither upstream or downstream. 14- 10= 4 and 10- 6= 4. Therefore the stream's current is 4 miles per hour.
Answer:
add 8
Step-by-step explanation:
-11 + 8 = -3
-3 + 8 = 5
5 + 8 = 13
